I wonder if any of you tennis pros out there can offer a tip to help with a problem my daughter is having. She changes her grip during her service motion. She starts with a continental grip and finishes her toss in conti, but during the remainder of the service motion to contact she regrips into an eastern forehand. It is a subconcious habit; she's tried to focus on not doing it and sometimes succeeds, but then it comes back pretty quickly. We've tried having her start in a BH grip (maybe she'd change to conti? Nope, she regripped to FH!), tried various tricks we'd read or gotten from local pros. She volleys in conti, but during her serve her I can see her fingers wiggle and then there she is in a forehand grip It is driving her nuts, and I'm at a loss how to help her further. Anyone else figure out how to correct such a habit? Thanks.
